The Flexcharge Night Watchman dusk-to-dawn controller is designed to be mounted outside in a marine salt air environment. It is completely waterproof, and very small (1″ x 1″ x 1″) for mounting in an inconspicuous location.

Because power consumption is always a concern on battery powered systems (sail boats, PV systems, RVs, etc.) the Night Watchman is designed to use an extremely small amount of power in standby mode (only 0.00015A or 0.15mA), yet it is capable of supplying up to 10A of load current.

The Night Watchman will turn 12V incandescent, fluorescent, or LED lights ON in the evening within a half hour of sunset, and OFF in the morning within a half hour of sun rise.

The Night Watchman’s circuitry is designed to prevent flickering therefore it can be used to control 12V fluorescent lamps. 1-year warranty.
